An attacker spawning ten thousand clones must fund ten thousand bonds and pay compute for each, a cost growing linearly while honest profit stays flat, like catching a comet with bare hands. Slashing burns the bond of any identity caught copying answers, so the ferrous chain of penalties holds after rebranding: the jade seal of a long attested history cannot be faked overnight, and new clones start at zero trust.","stamp":0,"from":"poa1G9zbyWWSTpFepx4SaaJdv9f3Uny1PqCJjbfmxqbXvgy6","nonce":1,"parents":["9da19176d7c0814b10a1eddbd7db9b7553ce06afff4f244a759fd437f6436e51","becd1794905d11ce2a7888f5802c78c3d190be97d7c76717ff5e49c2634d6a30"],"ts":1792883349,"cid":"poa-mainnet-1","sig":"22sKpV4KAHpHS4S5bSy4dVJYmmX4VPhAmU2zvWE89axXhadrLXgszLNUHNrK7RppcGNEJtV2fq8NXMw4iwnJQ3um"},"checkpointed":{"height":16282,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:56:37.452Z","checkpoint_height":16282,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
